A method of equivalent analysis for dynamics and statics behavior of honeycomb sandwich plates is obtained by using low\|order shear deformation theory. Equivalent modulus and equivalent density of an equivalent plate are given by means of this method. The difficulty is eliminated that dynamics and statics behavior of honeycomb sandwich plates can not be solved directly by using universal finite element programs such as well known NASTRAN. Results of analytic demonstration show that the equivalent method has a better accuracy of approximation.
